Rad-hard Processor
Atmel® Corporation announces the AT697, a radiation hardened 32-bit SPARC® processor (V8) for the space industry. Compared to the former SPARC processors, the AT697 improves the speed versus power consumption ratio by eight, providing the spacecraft computers with an increased calculation capacity in a three-time smaller package. The AT697 processor implements the LEON2 FT (fault tolerant) VHDL model owned by ESA, the European Space Agency. It is produced on the company’s 0.18µm CMOS process. It includes a SPARC V8 Integer Unit, a Floating Point Unit, separate instruction and data caches, a PCI interface and a flexible memory controller that can interface with SRAM, PROM and SDRAM. The device operates with 1.8 V and 3.3 V power supplies for the core and the I/O buffers, respectively. It delivers 86 MIPs (Dhrystone 2.1) and 23 MFlops (Whetstone) at 100 MHz. The ratio between performance and power consumption reaches a value as high as 150 MIPs/W, the power consumption being 7 mW/MHz.
